Replace Text within a Word document using IronPython

Below, the doc_replace_text method demonstrates how to replace text within a Word document. This is commonly used as a way to create dynamic, data-driven letters based on a template. The method accepts the name of the template Word document (source_filename), the tokens to look for, the values to replace tokens with, and the destination filename.

Using COM Interop, the template Word document (source_filename) is opened, and the StoryRanges are looped through, replacing found tokens with their corresponding values. The result is then saved as the destination_filename.
